The next is an in depth comparison of their critical overall performance indicators, supporting you speedily grasp the Main variances.
two.1 Lubrication Effectiveness: hBN Has an Undisputed Advantage
Lubrication efficiency is definitely the core advantage of hBN. As a consequence of its layered crystal construction, the layers can slide freely underneath exterior force, forming a stable lubricating film to the area from the friction pair, which appreciably reduces friction coefficient and dress in. Beneath unique working situations, hBN’s lubrication effectiveness reveals obvious benefits:
Below seawater lubrication situations, the friction coefficient on the Si₃N₄-10 vol% hBN friction pair might be as low as 0.03, as well as the use amount is as little as 10⁻⁶ mm/nm. This really is a result of the thorough result of hydrodynamic lubrication and boundary lubrication in the surface movie shaped by tribochemical reaction. Less than whole immersion drinking water lubrication, the friction coefficient in the Si₃N₄-hBN/Si₃N₄ friction pair may be as little as 0.01, and that is much reduce than that of pure Si₃N₄ (0.35 underneath the very same situations).
In distinction, Si₃N₄ has no clear lubrication overall performance. Its friction coefficient is pretty significant (typically 0.fifteen-0.35 below dry friction), and it really should be applied with lubricating oil or grease in friction scenarios. Having said that, in large-temperature, superior-strain, or vacuum environments wherever lubricating oil cannot be made use of, Si₃N₄’s friction and put on complications will grow to be popular, which limits its application in a few Exclusive lubrication scenarios.
It really is truly worth noting which the addition of a small quantity of hBN can Enhance the densification strategy of Si₃N₄ composite ceramics to a particular extent, thus improving upon the general Vickers hardness, however it will even decrease the mechanical power of Si₃N₄ to a particular extent.
